Random questions/musings - new batteries, genny, charger...

Pianotuna

Thanks for the info and links, as well as the monitor suggestion on pm. Unfortunately I'd already ordered the tm2025 and shunt. I don't waste time, lol. The current available space I have for arteries is 20x14x10 - though I could easily expand that. Seems to be sufficient room for one 250 ah agm battery. A quick guesstimate suggest that should easily provide 4 days power before taking the agm down to the 50% point, without any recharging. Any suggestions in the battery department?
